## Arti (Tor's Rust Implementation)

### Timestamp Tracking for RetryError :Rust:
 
This enables developers and operators to see precisely when each failure occurred and measure how long retry sequences lasted meaningfully improving debuggability of connection failures in a privacy-critical networking stack.

https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3506

### SOCKS5 Proxy Support :Rust:

Implemented SOCKS5 proxy functionality in Arti, contributing to one of the core interoperability features needed for Arti to serve as a drop-in replacement for the C Tor client. SOCKS5 is the primary protocol through which applications route traffic over Tor.

https://gitlab.torproject.org/tpo/core/arti/-/merge_requests/3681

### HTTP CONNECT Proxy :Rust:

Added HTTP CONNECT proxy support to Arti, enabling HTTP-based clients and tools to tunnel connections through Arti without requiring SOCKS support. This expands compatibility with a broad class of software that relies on the HTTP CONNECT method for proxying.

## Onion Services

### Arti Integration for Onion v3 Key Generation — OnionMine :Rust:

Integrated Arti's cryptographic primitives into OnionMine to support onion v3 (ed25519-based) key generation. This replaces reliance on older tooling and aligns the project with the modern, more secure v3 onion address standard.

https://gitlab.torproject.org/tpo/onion-services/onionmine/-/merge_requests/58

### Docker Image Size Reduced by 80% — OnionMine :Docker:

Optimized the OnionMine Docker image, shrinking it by 80% and cutting build times by ~15 seconds. Achieved through multi-stage builds and dependency pruning — directly improving CI pipeline speed and deployment efficiency.

https://gitlab.torproject.org/tpo/onion-services/onionmine/-/merge_requests/54

### Arch Linux Build & AUR Package — OnionSpray :Arch Linux: :Shell:

Added Arch Linux build support and published an [AUR](https://nihal.is-a.dev/projects/pkgbuilds) package for OnionSpray, making the tool accessible to the large Arch Linux user base without requiring manually building the project.

https://gitlab.torproject.org/tpo/onion-services/onionspray/-/merge_requests/140

:linux: Qubes OS is a security-focused operating system that protects your digital life through compartmentalization. Rather than running everything in one shared space, it divides your computer into isolated virtual machines called "qubes" -- think of them as separate, secure rooms. If malware infects your web browser, it stays trapped in that single qube and cannot access your email, files, or other applications.

![qubesos-trustlevel-architecture](https://doc.qubes-os.org/en/latest/_images/qubes-trust-level-architecture.png)

Most operating systems try to prevent every possible attack, but Qubes takes a different approach: it assumes compromises will happen and focuses on containing the damage. This means journalists, researchers, privacy advocates, and :privacytech: security-conscious professionals can use their computers with confidence, knowing that a breach in one area won't compromise everything else. Each qube displays with its own colored window border so you always know which environment you're working in.

My Contributions:

- **Bug Fix:** Fixed a false-positive reboot prompt in :debian: templates when using the dom0-provided kernel — `needrestart`'s `kernelhints` was comparing the running kernel against `/boot`, which always differs in this configuration. Disabled `kernelhints` via `50_qubes.conf` when dom0 kernel mode is active  
  [qubes-core-agent-linux #645](https://github.com/QubesOS/qubes-core-agent-linux/pull/645)

- **Feature:** Added an optional comment/notes field to firewall rules in Qubes Manager, closing a feature request open since 2015 (issue #952). Comments are stored as metadata and don't affect firewall behavior;
  [qubes-manager #447](https://github.com/QubesOS/qubes-manager/pull/447)

- **Security Fix:** Prevented `qvm-device` from attaching devices to dom0 without an explicit `--force` flag, adding a safeguard against accidental attachment to the privileged domain. Implemented across both the core admin layer and the admin client :cli: CLI  
  [qubes-core-admin #798](https://github.com/QubesOS/qubes-core-admin/pull/798) · [qubes-core-admin-client #466](https://github.com/QubesOS/qubes-core-admin-client/pull/466)

- **Feature:** Added a Qubes-specific extrepo configuration for :debian: templates, using `config-package-dev` displacement to avoid conflicts with the upstream `extrepo` package. The configuration points extrepo at local offline data by default, enabling users to safely add external repositories (e.g., Signal, Element) in templates without direct network access or manual GPG key management. 
  [qubes-core-agent-linux #648](https://github.com/QubesOS/qubes-core-agent-linux/pull/648)

- **Docs:** Simplified and de-alarmed the :fedora: and :debian: template upgrade documentation, reducing friction for users who felt intimidated by the existing warning-heavy language  
  [qubes-doc #1662](https://github.com/QubesOS/qubes-doc/pull/1662)

- **Bug Fix / Consistency:** Renamed `--app` to `--apps` in `qubesctl` for consistency, with matching documentation update  
  [qubes-mgmt-salt #45](https://github.com/QubesOS/qubes-mgmt-salt/pull/45) · [qubes-doc #1672](https://github.com/QubesOS/qubes-doc/pull/1672)

## Zed :rust:

My first editor was Atom, and it shaped how I think about developer tooling. Years later, contributing to Zed - built by some of the same people who shaped Atom - feels like a full-circle moment.

I have been using Zed for over a year. The speed is astounding. This contribution journey began while developing an MCP extension for the Arch Linux package server. During extension development, I found a bug in the configuration modal, reported it, and started working on a fix - only to find someone had already submitted a patch. Perks of an active community. Rather than discard the setup effort, I tackled another issue I had personally encountered, and things snowballed from there.

What started as one extension contribution grew into a sustained series of contributions and selection in the **[Zed Guild](https://zed.dev/community/zed-guild)** program, spanning terminal rendering, the debugger, font infrastructure, Linux platform integration, and the git UI - both features and fixes.

---

### Features

- **Linux Global Menu Bar** - Implemented native global menu bar support for Linux (X11 and Wayland) via the D-Bus protocol, enabling desktop environment integration on KDE Plasma, GNOME (with AppIndicator), Unity, and compatible DEs. Involved hooking into GPUI's action system and translating it into D-Bus menu trees at runtime.  
    [Pull Request #51321](https://github.com/zed-industries/zed/pull/51321)
    
- **Browser / WebView Tab** - Prototyped a native browser tab inside Zed using the system webview via `wry` (Tauri's cross-platform webview library), composited as a native child view within GPUI's window. A proof-of-concept exploring GPUI's compositing model for embedding non-GPU-rendered surfaces.  
    [Pull Request #52447](https://github.com/zed-industries/zed/pull/52447)
    
- **Buffer Letter Spacing** - Threaded a new `buffer_letter_spacing` setting through GPUI's text layout, shaping, and platform text backends, and wired it into the editor's rendering and line-wrapping pipeline so layout, hit-testing, and cursor positioning all stay consistent. Revived and extended a previously approved-but-stalled PR.  
    [Pull Request #53542](https://github.com/zed-industries/zed/pull/53542)
    
- **Pin / Unpin Recent Projects** - Added pin and unpin support to the recent projects panel, allowing users to anchor frequently-used workspaces so they persist regardless of recency ordering.  
    [Pull Request #52103](https://github.com/zed-industries/zed/pull/52103)
    
- **Vim Navigation in Git Graph** - Wired up Vim mode navigation (`j`, `k`, `gg`, `G`) in the Git Graph view, making it consistent with the rest of Zed's Vim bindings.  
    [Pull Request #53609](https://github.com/zed-industries/zed/pull/53609)
    
- **Ctrl+Click in Terminal** - Implemented interactive terminal output parsing with Ctrl+Click navigation and drag selection, enabling instant file/line jumps from error messages and stack traces.  
    [Pull Request #42526](https://github.com/zed-industries/zed/pull/42526)

### Bug Fixes

- **Debugger: Offline Cache** - Diagnosed and fixed the debugger failing entirely when Zed runs without network access. The fix ensures the debugger falls back to a locally cached adapter rather than aborting.  
    [Issue #45781](https://github.com/zed-industries/zed/issues/45781) · [Pull Request #50928](https://github.com/zed-industries/zed/pull/50928)
    
- **Debugger: Local Fallback** - Fixed the debugger failing to locate a locally installed `debugpy` when offline, causing silent breakage for Python debugging workflows. The fix wires in a proper local lookup path.  
    [Pull Request #51696](https://github.com/zed-industries/zed/pull/51696)
    
- **Linux Auto-Updater Error Surfacing** - Previously, missing system dependency failures during auto-update would silently return to idle with no user guidance. Fixed the error path to surface actionable feedback.  
    [Pull Request #50637](https://github.com/zed-industries/zed/pull/50637)
    
- **Terminal True-Color Rendering** - Fixed true-color rendering in the terminal where Zed's APCA contrast adjustment algorithm was washing out explicitly-specified 24-bit colors, overriding what the application had set.  
    [Pull Request #52162](https://github.com/zed-industries/zed/pull/52162)
    
- **Git Panel: Trash Untracked Files** - Fixed a silent failure when trashing untracked files from the git panel while a repository subdirectory (rather than the repo root) was open as the workspace root.  
    [Pull Request #51161](https://github.com/zed-industries/zed/pull/51161)
    

---

### Bug Reports

- **Launchpad Viewport Shift on Panel Resize** - Identified and documented a rendering issue where resizing the terminal panel incorrectly shifts the background Launchpad view, affecting users with workspace restoration enabled.  
    [Issue #52145](https://github.com/zed-industries/zed/issues/52145)
    
- **Git Graph: Vim Navigation Missing** - Reported the absence of Vim mode support in the Git Graph view, which I subsequently fixed.  
    [Issue #53525](https://github.com/zed-industries/zed/issues/53525)
    
- **Docs Search Bar Keyboard Navigation** - Identified a keyboard navigation failure on zed.dev/docs where the search results pane fails to scroll with arrow keys, leaving keyboard-driven users stranded.  
    [Issue #50604](https://github.com/zed-industries/zed/issues/50604)
    
- **Extension Configuration Modal Scroll** - Identified viewport rendering issues in the context server configuration modal affecting scroll behavior and height calculations.  
    [Issue #42342](https://github.com/zed-industries/zed/issues/42342)

# Core Problem Solved:

The Arch User Repository (AUR) comprises user-submitted packages that are occasionally unverified. It relies on end users to perform manual safety checks before installation. Arch MCP addresses this issue by allowing users to express their intentions in natural language. The AI then analyzes this input to provide intelligent recommendations, empowering users to make well-informed decisions.

### Protocol Implementation & Architecture

- **MCP Server Development**: Built custom MCP server implementing the full protocol specification (resources, tools, prompts)
- **JSON-RPC 2.0 Transport**: Bidirectional client-server communication with lifecycle management
- **Cross-Platform Compatibility**: Works on both :archlinux: and non-:archlinux: systems 
- **Multi-Transport Support**: STDIO and HTTP transports for flexible deployment scenarios

### Security-First Engineering

- **PKGBUILD Static Analysis Engine**: 50+ security checks detecting malicious patterns (curl pipes, privilege escalation, data exfiltration)
- **Package Trust Scoring**: Multi-factor risk assessment (maintainer reputation, vote count, last updated, out-of-date flags)
- **Sandboxed Execution**: No direct package installation—AI provides analyzed data for informed user decisions
- **Safe-by-Design**: Operations referencing only official :archlinux: sources (wiki, repos, AUR API)

### Key Features & Capabilities

- **Package Lifecycle**: Search, install (with security checks), remove, update checking with dry-run validation
- **System Monitoring**: Disk space analysis, failed services detection, boot logs, transaction history
- **Security Analysis**: PKGBUILD scanning, package integrity verification, orphan detection
- **Mirror Management**: Speed testing, health checks, fastest mirror suggestions by geolocation
- **Documentation Access**: Arch Wiki search with relevance ranking, news monitoring for critical updates

**Intelligent Workflows (Prompts):**
- **Safe System Update**: Multi-stage workflow (critical news check → disk space → update listing → service verification)
- **AUR Package Audit**: Pre-installation security workflow (metadata analysis → PKGBUILD scan → risk report)
- **Dependency Analysis**: Installation planning with repository checks and dependency mapping
- **Troubleshooting Assistant**: Keyword extraction → Wiki search → contextual recommendations

**Asynchronous Design**
- Non-blocking I/O for concurrent Wiki/AUR/Repo queries
- Async :python: HTTP client for parallel mirror speed testing
- Stream-based log parsing for real-time system diagnostics

![zingat-diagram](https://github.com/nihalxkumar/zingat/raw/main/assets/zingatdiagram.png)

Zingat

The infrastructure uses Infrastructure-as-Code principles with :ansible: for bare-metal provisioning and :argocd: for continuous deployment, enabling reproducible, version-controlled infrastructure management.

The entire stack—from OS-level security hardening to application deployments—is managed through declarative configuration files. Changes flow through :git: commits that trigger automated validation pipelines and :argocd: synchronization, ensuring the cluster state always matches the repository.

### Technical Architecture

Kubernetes Platform (K3s)

The cluster runs K3s v1.30.2, a lightweight :kubernetes: distribution optimized for edge and single-node deployments. Configuration includes custom TLS SANs for remote API access, disabled bundled Traefik (replaced with a custom deployment), and local-path storage for persistent volumes.

GitOps Deployment (ArgoCD)

:argocd: implements an app-of-apps pattern for hierarchical deployment management:

- Root Application: Syncs infrastructure components (Traefik, :terraform:, monitoring)
- ApplicationSet: Dynamically creates Applications for each service in kubernetes/apps/
- :helm: (Kustomize): Provides layered configuration with base manifests and environment overlays
- Auto-sync: Enabled with pruning and self-heal for drift detection

All changes to the cluster must pass through :git:, eliminating manual kubectl apply operations and ensuring full audit trails.

CI/CD Pipeline (:gitlab:)

A three-stage pipeline validates every merge request:

| Stage | Checks |
|-------|--------|
| Lint | :ansible: playbook linting, README validation |
| Validate | Kustomize build verification, :kubernetes: schema validation |
| Security | detect-secrets scanning, SOPS encryption verification |

Renovate bot automates dependency updates with staged rollout policies—patch updates auto-merge after 7 days, while major updates require monthly review.

Ingress & TLS (Traefik + cert-manager)

Traefik serves as the ingress controller with TLS termination via cert-manager. Certificate issuance uses Let's Encrypt DNS-01 challenges through Cloudflare API tokens, enabling wildcard certificates for *.nihalxkumar.dev without exposing HTTP-01 challenge endpoints. A custom tailscale-only middleware restricts internal services to the Tailscale tailnet CIDR (100.64.0.0/10), while the public dashboard uses standard TLS with Let's Encrypt certificates.

Network Security (Tailscale + UFW)

A multi-layered security approach:
- VPN Access: Tailscale operator enables MagicDNS for secure service exposure via tailnet
- Firewall: UFW rules configured via :ansible:—default deny incoming, explicit allow for :kubernetes: API (6443), HTTP/HTTPS, pod/service CIDRs (10.42.0.0/16, 10.43.0.0/16), and VXLAN overlay (8472/udp)
- SSH Hardening: Root login disabled, password authentication disabled, key-only access via Tailscale interface
- Network Policies: :kubernetes:-native segmentation (e.g., :n8n: only accepts traffic from traefik, tailscale, and monitoring namespaces)

External traffic flows through Cloudflare Tunnel → localhost:443 → Traefik → services, providing DDoS protection and WAF without exposing the VPS IP.

Observability Stack

:prometheus: and :grafana: provide metrics collection and visualization with pre-configured dashboards for Traefik, :argocd:, and node metrics. Axiom aggregates logs via Fluent-bit DaemonSet, collecting systemd journal and container logs with :kubernetes: metadata enrichment (pod, namespace labels). All monitoring components use Tailscale ingress for secure access.

Secrets Management (SOPS + Age)

All secrets are encrypted at rest using SOPS with Age encryption keys. The repository enforces this via CI pipeline—files in secrets/ directories must use .sops.yaml extension, and the pipeline verifies SOPS envelope presence before merge. KSOPS (:kustomize: SOPS generator) decrypts secrets at build time, integrating seamlessly with :argocd:'s GitOps workflow.

Infrastructure as Code (:ansible:)

Four playbooks handle bare-metal provisioning:

| Playbook | Purpose |
|----------|---------|
| k3s.yml | :kubernetes: installation, kubeconfig setup, prerequisites (open-iscsi, nfs-common) |
| security.yml | UFW firewall rules, SSH hardening, fail2ban installation |
| tailscale.yml | VPN client installation, MagicDNS configuration |
| dns-tunnel.yml | Cloudflare Tunnel setup for public DNS routing |

Variables are managed via :ansible: Vault with a .vault_pass file, ensuring sensitive values (Tailscale auth keys, Cloudflare tokens) are encrypted in the repository.

## Overview

Arch Linux :ArchLinux: is a lightweight, rolling-release Linux distribution favored by developers for its minimalist design philosophy and cutting-edge software packages. Unlike distributions that bundle pre-compiled software, Arch provides users with powerful package management tools and expects them to build their system to their exact specifications.

The Arch User Repository (AUR) is a community-maintained repository containing over 85,000 user-contributed packages making it one of the largest software repositories in the Linux ecosystem. The AUR serves millions of Arch Linux users worldwide, providing access to software ranging from bleeding-edge development tools to specialized scientific applications. The ecosystem thrives on user contributions, encouraging collaboration and knowledge sharing.

Each AUR package requires writing PKGBUILDs - specialized bash scripts that automate source fetching, dependency resolution, compilation, and installation. This demands deep understanding of build systems (Make, CMake, Meson), compilation flags, and cross-platform compatibility.

Maintaining packages requires git workflows, semantic versioning, tracking upstream changes, writing clear installation instructions, maintaining changelogs, testing packages across different system configurations, handling edge cases, and ensuring reproducible builds. This entire process develops the quality-focused mindset essential for shipping reliable software.

I also review packages submitted by other maintainers.

## Technical Highlights

**Core Skills:** Shell Scripting • Package Management • Build Systems • Dependency Resolution

## Process

- Understanding codebase of the source repository
- Writing maintainable build scripts (PKGBUILD)
- Handling diverse build systems (`make`, `cargo`, `npm`, `pip`, etc)
- Managing dependencies (`makedepends`, `depends`, `optdepends`)
- Implementing version schemes (`pkgver` functions, VCS packages)
- Creating installation hooks and file placements
- Test builds in clean `chroot` environments
- Monitoring upstream projects for new releases
- Reporting issues to upstream maintainers
- Contributing patches when needed
- Act on community feedback

This entire process develops the quality-focused mindset essential for shipping reliable software.

## Philosophy

Ever since I took my first breath, I’ve relied on communities. It’s the shared support of individuals; each contributing their part in a collaborative effort that allows us all to grow. I believe and work on building open spaces where people can learn, grow, and solve important problems together.

## Active Community Building

In my first semester, I noticed a gap that students from previous batches had no organized peer community/platform to talk on. I took the initiative to build one from the ground up. Created a **Discord Server** and a **Matrix Space** which now consists of **900+ members** through persistent outreach and explainer sessions. Along with that, I created a [GitHub Organization](https://github.com/bits-bsc-cs) to work on projects together, which saw light to a [discord bot](https://github.com/bits-bsc-cs/discord-bot), along with a [LinkedIn Group](https://www.linkedin.com/groups/14460056/). Our community is uniquely diverse; members aged 16–65, including career starters, career changers, and lifelong learners.

A lot of collective time and effort has been spent in building this the best student discord community server ever. Together, A supportive environment was created where students and professionals, from first-years to alumni, can connect, share knowledge, and learn from one another.

## Passive Community Building

These days (Nov '25) I actively participate in [Ente](https://ente.io), [FOSS United and its related groups](https://fossunited.org/), [KDE India](https://kde.org/), [Rust Delhi](https://www.meetup.com/rustdelhi/), [OSM India](https://www.openstreetmap.in/), [FSCI](https://fsci.in/) and other privacy communities under disguised names.

These contributions go beyond code. I engage in discussions that actually are important for all of us. I believe in the power of collaborative effort to solve problems that no individual could tackle alone.
